An animal model of portal hypertension by partial portal
vein ligature was created in seven pigs and evaluated by
4D Flow MRI using PC-VIPR, a radially undersampled
acquisition scheme. During the operative procedure,
vessels were assessed by perivascular ultrasound to
provide an unprecedented in-vivo comparison of 4D Flow
MRI to a reference standard. PHTN was successfully
created, results show a good agreement of US and 4D Flow
MRI using PC-VIPR.
